Hi!  what will you do with the flowers, are you going to grow them for a research study or just submit a written report about it's development info? In addition to that, different flowers also have different climatic requirements and etc, so you could be more specific into which flowers do you usually grow in your country and the ones you want to focus because there's a lot of  it with different growth requirements.

thank you for answered me. In fact i wana evaluate the dez basin(south-west in iran) crops water requirement with cropwat. This basin have more than 30 crops that i successfully evaluate the 29 crops need. But finale crop is the rose and i Don't know what's the rose information like development days or yield response. I hope you have a source that can help me. This is all for my thesis for master of science.
